Never resolving promises

[simonguldstrand]

Hi,

When running:
exports.handler = (event, context) => { return serverlessExpress.proxy(server, event, context) }
My server exits without timeout, but I don't go through my whole event loop, i.e, I don't resolve all promises.

When I run:
exports.handler = (event, context) => { return serverlessExpress.proxy(server, event, context, 'PROMISE').promise }
I execute all my promises, I see all outputs in the right places and go through all operations. But my function times out.

What am I doing wrong?

What parts of the code do you want to see?

index.js

const awsServerlessExpress = require('aws-serverless-express')
const app = require('./main.js')
const server = awsServerlessExpress.createServer(app, null)

exports.handler = (event, context) => {
  return awsServerlessExpress.proxy(server, event, context, 'PROMISE').promise
}

main.js

require('dotenv').config()
var app = require('express')()

const awsServerlessExpressMiddleware = require('aws-serverless-express/middleware')
app.use(awsServerlessExpressMiddleware.eventContext())

app.get('/', (req, res) => {
  res.json(req.apiGateway.event)
})

module.exports = app

I am running node v12.16.1

I launch my test like this:

"scripts": { "test": "run-local-lambda --file index.js --event event.json --timeout 3" },

Thankful for any help, I am so stuck and can't find any help on the internet

I also created an entirely fresh project with the files from example. Not waiting for function myFunc () { console.log('hey') } setTimeout(myFunc, 3000) when I run without 'PROMISE'

If I run with 'PROMISE' it times out even if I set 30 seconds when running the local script with run-local-lambda.

This problem is identical when running serverless-http package also. It never resolves with promises.

Maybe the comments in issue #134 can help you and other developers.

I finally used a callback to avoid the timeout.
